This question has more to do with db designs than code. What you need to do is create a 'checkpoint' table for the x_world table. Each entry in the checkpoint will have a unique data 'signature' for the 7 days worth of data. If you are using sql server, you can use a combination of binary_checksum() and CHECKSUM_AGG() .
In your example, autoID in the checkpoint is the foreign key to the x_world table. Once you have this setup, the SQL part to determine if there was a change in the 7-day data and which row(s) had changed is really easy. -----Original Message----- From: Andy Matthews [mailto:[EMAIL PROTECTED] Sent: Thursday, June 08, 2006 6:18 AM To: CF-Talk Subject: Find which records have changed over a 7 day period. Anyone care to chime in on this? I've posted a thread which hasn't gotten many responses yet and I'm wondering if any of you SQL wizards have input. http://www.sitepoint.com/forums/showthread.php?t=389438 <!----------------//------ andy matthews web developer certified advanced coldfusion programmer ICGLink, Inc.
